Strips or Wraps? and Door Rail Shadows

[nwav8tor]

I want to surface mount twenty 48" dual bulb T8 fixtures in my 800 sq ft garage. Ceiling height is 9'. I plan 3 rows of 3 fixtures each with 2' lengthwise between fixtures in the double car bay and 2 rows of 4 fixtures each also with 2' spacing in the longer single car bay. 3 more fixtures will be placed perpendicularly between the rows near the back wall opposite the garage doors (2 in the double bay and 1 in the single bay). Power will be supplied through two 15A circuits; one for the 11 fixtures in the double bay and one for the 9 fixtures in the single bay. Each car bay will have it's own lighting switch.

I hope to be able to just pull the wire through the sheetrock ceiling and make the connections inside the fixtures themselves. I understand that the fixtures have to be rated for that use.

My questions to all of you are:

1) Would you use strip light fixtures or wraparound fixtures for this type of install?

The first light in the outer rows of each bay will be mounted about 18" directly above the garage door track rails. With the doors in the open position I think one bulb of the fixture will throw at least some light down past the door. I'm not too worried about that since if enough light wasn't coming through the door opening, I'd just close the door to get the added light from the now unblocked fixture. However,

2) With the door closed, would the door rails block significant amounts of light or cast shadows? Anyone have experience with this?

Thanks for all your comments...

Wraps. With a 9 ft ceiling, anything long you're swinging over your head and crash goes the fluorescent bulb showering glass bits on your head.
